The energy absorption control characteristics of Al thin-walled tube under quasi-static axial compression

The Effect of Cone Angle on Composite Tubes Subjected to Axial Loading

“…They also studied the effect of fiber type, and found that carbon fiber/epoxy possess the highest loadabsorbing capacity. Lee et al [16] experimentally investigated the energy absorption characteristics of thin-walled square tubes that are under quasi-static axial loading for the purpose of coming up with the optimal structural configuration of vehicles that provides maximum safety to occupants in the event of a collision. The result of the static collapse test showed that the amount of energy absorption and mean collapse load of the thin-walled tubes is increasing, and it depends on the thickness-towidth ratio.…”

The Effect of Stress Wave on Dynamic Response of Square Thin-Walled Tube

“…And there is also lots of work has been done on the failure mode, initial peak and energy absorption of the thin-wall tubes subjected to quasi-static or low speed impact loading in the past decades. The deformation mechanism of thin-wall tube under quasi-static or low speed impact loading is well-known [1][2][3][4][5][6][7][8]. And the initial peak and energy absorption of tubes in the quasi-static loading can be predicted.…”

Energy absorption of thin-walled empty and foam-filled tubes

“…Other geometrical shapes of thin-walled extrusion have been extensively studied [9][10][11][12], especially on the polygonal shapes. However, the crosssectional shapes studied were restricted to square [41,44,50], hexagon [51], octagon [43,52] or multi-corner convex column [53,54]. Although the collapse modes of square tubes are quite different from those in circular tubes [41], the general characteristics of F- curves are similar [32] where is the angle of rotation of the side panels,  is the angle between travelling hinge and tube axis and  is the angle between sides of the collapse tube and travelling hinge, respectively.…”
